I'd start with your 9 volt power supply. Try a different 9 volt supply or battery.

...i already tried a fresh 9v battery and a BOSS PS120S power supply...the distortion seems to go away with 12v power supply only...

The only thing I can think of is more voltage usually equates to more headroom. As to why this distortion is just starting now? I wonder if swapping out the NJM4560 with a better spec'd op amp would help?
